Singer Dionne Warwick’s sister, Dee Dee Warwick, has been named as a person who molested Whitney Houston in a new documentary that premiered at Cannes on Thursday.

In the documentary Whitney, the singer’s longtime assistant, Mary Jones, says that Houston confided in her and told her about the molestation, which happened when she was a child. But Houston wasn’t the only family member who experienced molestation. Houston’s brother, Gary Garland-Houston, said that he was also molested as a child.

Kevin Macdonald, the director of Whitney, told Indiewire that it was Whitney Houston’s brother who told him that she might have been molested by Dee Dee, after revealing that he himself was.
